Q.1	Alex, an aspiring marine conservationist, embarked on a mission to address the threats to coral reefs. He studied the factors causing coral bleaching and sought effective solutions. While researching coral bleaching, Alex found a strategy that could directly aid in protecting coral reefs. What approach would be most beneficial for addressing this issue?
	a) Regulating whaling activities in the vicinity of coral reefs.		b) Studying and protecting endangered species in the area.
	c) Reducing ocean acidification through global policy changes.		d) Establishing marine protected areas around coral reef habitats.

Q.2	Lucas decided to explore the forest and uncover its mysteries. Amidst his exploration, Lucas met an elder from his village who shared wisdom about the forest's significance. What role does the forest play in soil erosion?
	a) The forest has no impact on soil erosion or land stability.		b) It contributes to soil erosion by retaining excess water.
	c) It acts as a shield against soil erosion and maintains land stability.		d) It promotes landslides due to dense vegetation.

Q.3	Your closet is overflowing with clothes you rarely wear. How can you reuse these items instead of throwing them away? 1. Donate them to charity for someone else to enjoy. 2. Upcycle them into new creations like tote bags or pillowcases. 3. Host a clothing swap with friends to exchange unwanted items.
	a) Only 1		b) Only 2
	c) Only 2 and 3		d) 1, 2 and 3

Q.4	While exploring climate change's impact on ocean health, a group of students identified a process significantly contributing to ocean acidification. What aspect of climate change primarily leads to the acidification of the ocean, affecting marine organisms?
	a) Decreased levels of greenhouse gases in the atmosphere.		b) Elevated ocean temperatures foster favourable conditions for marine life.
	c) Increased carbon dioxide absorption by the oceans, altering their pH levels.		d) Reduced water pollution due to stricter environmental regulations.

Q.5	An individual aims to make more environmentally conscious choices in their daily consumption. What habit should they adopt to support this goal?
	a) Regularly discarding and replacing electronic devices		b) Prioritising products with excessive packaging for better protection
	c) Opting for products made from recycled or sustainable materials		d) Buying single-use plastic items in large quantities for convenience
